Texas Instruments SN74FB1653 17-Bit LVTTL/BTL Universal Storage Transceivers With Buffered Clock Lines SN74FB1653PCA

The SN74FB1653PCA is a 17-bit universal storage transceiver designed for LVTTL and BTL signal levels, compliant with IEEE Std 1194.1-1991. It features an 8-bit and a 9-bit transceiver with buffered clock lines, facilitating signal translation between LVTTL and BTL environments. The A port operates at LVTTL levels, while the B port utilizes BTL levels, with open-collector outputs capable of sinking up to 100 mA. The device includes selectable clock delay options and supports high-impedance states during power-up and power-down. It is suitable for applications requiring reliable data transfer and signal integrity in mixed-voltage environments. Enhanced heat-dissipation techniques are recommended for high-frequency operations exceeding 50 MHz. The SN74FB1653PCA is housed in a TQFP package and operates within a temperature range of 0¬8C to 70¬8C.
